them to be reversed completely about their axis, although such completereversal is prevented after the vanes have reached the extreme positionallowed by the abutments previouslyl referred to. These abutmentscomprise an abutment 47 secured in a suitable position to thecircumferential rim 21, and a spur 46 secured to the correspondingreinforcing spoke 20 adjacent the said ring 21, as shown in Figure 4.Furthermore, in order to steady the vanes and keep the parts in therequired relative position, a set of steadying coil springs 42 areattached on the one hand to aforesaid fixing disc 43 and on the otherhand to the flange ofsleeve 36, said springs 42 tending to bring thesleeve 36 back towards the hub 18.

The described apparatus is completed by a rudder tail including a frame7 2v attached by means of bolts 73 and 74 to the members 9 of thecarriage and by means of bolts 7 5 to the upper portion of the bridge12, 52, 53 previously mentioned. rIhe said framer carries ak verticalrudder 7 6,' and kthe, action of the Wind on the lat-ter causes therotation of the carriage 9 carrying the complete apparatus about thetubular member 2 so as to maintain automatically the vane wheel in theposition in which it. is exposed tothe full action of the wind.

lhe whole central mechanism should preferably be covered by a sheetmetal casing, in order to protect it against weather conditions, andthebearings 15 and 16 shouldv be similarly protected' againstpenetration of water.V

I claim y i In a Wind-motor of the type set forth, comprising avane-wheel with pivoted vanes on a shaft carried by a turning carriage,and

means iniiuenced by centrifugal force for adjusting the angular positionof the vanes according to the velocity of the wind, abutments on the rimof the wheel, `for limiting the Jtwo extreme angular positions of eachvane, a disc secured to the outer end of the i,

vane-wheel shaft, a set of coil springs attached on the one hand to thesaid disc and on the other hand to the slidable collar on,

the vane-wheel shaft and forming a part of the aforesaid meansinfluenced by centrifugal force, and a second set of coil springsattached on the one hand to the aforesaid disc and on the other hand toa rigid operating my name. L
